基于PBL的协同小组分工教－学法在草地保护学实践教学中的应用

以河北农业大学动物科技学院草业科学专业两届学生(实施不同实践教学方法)为例，在拓展实验教学途径、课程实践技能比赛、校外教学实习、企业家实践教学协同指导小组、创新草地保护学实习内容、实践教学信息化改革及课程评价体系等方面进行实践教学改革，在各教学环节实施基于PBL协同小组分工教–学法，探讨产、学、研、地协同背景下，团队协作学习为主的项目导向(project-based learning，PBL)教学法在草地保护学课程实践教学中的应用效果。结果表明：这种教学方法在很大程度上提高了学生考试成绩和教学质量，增强了学生综合专业实践素养，应在草地保护学教学中广泛推广。

Application of a teaching-learning method based on PBL collaborative group division of labor in practical teaching of grassland conservation

In this paper, two students majoring in Pratacultural Science in the College of Animal Science and Technology of the Agricultural University of Hebei (with different teaching practices) were taken as a study sample for practical application of teaching reforms aimed at expanding experimental teaching approaches, introducing course practice skills competitions, practicing teaching off campus, establishing a collaborative steering group made up of entrepreneurs, developing innovative content for teaching of grassland protection practices, practicing teaching informatization reform, and developing a course evaluation system to assess the effects of incorporating PBL (Problem-based learning) into teaching-learning methods used to teach a Grassland Conservation Course under the auspices of collaboration between industry, education, research, and local communities. Our results indicate that this teaching method can improve teaching quality and student test scores to a great extent, and enhance students’ comprehensive professional practice quality. Thus it should be widely promoted in the teaching of “grassland protection”.
